Sorry, no, what you posted is what YOU need. We do just fine without that, and AK has specific rules about Ebay, CL, and other sales links. AK does not allow links that point to your own auctions either. The AK site doesn't need to be a shill or advertising for any other site, pay or free. If that is from SH's site, great, that's their policy, and you're very welcome, no, encouraged to put your stuff on ebay, and then point to it from SH forum. I'm sure they would welcome your "contributions".
AK is a private forum site. It is owned and run by dedicated and volunteer folks. They set the rules, and if you want to be here, you abide by the rules. We work with the forums that we are given. If we lose a forum, there is a good reason for that. If we gain a forum, there is a good reason for that too. However, private forums are not democracies. We are guests here, and IMHO, we should behave as guests.
As I said before to you in the thread that was lost in the recovery, you are very welcome to start your own discussion forum or selling site, run it for 13 years, and offer people the options to push / sell anything to your members, if you have any. And you can let them do it for free. While you are trying to figure out how to pay for the computers, storage, bandwidth, hosting, software, and your staff that help you.
If you cannot abide by the rules (please read them again) and refrain from comments about moderation or administrative decisions, then you'll probably lose your guest status.
